In the moving film, the nurse is represented by a glowing orb of light, arriving at sunset and moving around different households at night to provide comfort to patients. It's only the next morning that we see that the light is actually a person (a real life Marie Curie nurse, Elizabeth Woolley). As she comforts the patient's daughter, we're reminded that Marie Curie nurses work through the night to provide "light in the darkest hours."

Created by Saatchi & Saatchi London and post-produced by MPC, the film was shot with real lightbulbs to create natural contact lighting on the skin and surrounding environment. The light rigging was removed in post-production and MPC VFX supervisor Marcus Dryden worked closely with the director to develop the light by repurposing the cluster of light bulbs to create one shining beacon.
